SAP获利能⼒报表常⽤Tcode的区别
1. KE30：执⾏报表，COPA的常⽤报表（实际数据和计划数据），即：实际数据报表和计划数据报表可在KE30中显⽰。
2. KE91和KE31的区别：KE91是⽤来创建基于⾏项⽬的COPA报表（数据取⾃⾏项⽬表CE1XXXX和获利段表CE4XXXX，其
中：XXXX为经营范围代码）；KE31是⽤来创建获利能⼒段的报表（该类报表的特性只能取KEQ3/KEQ4中的可⽤的获利能⼒特性，若KEQ3中将某特性设置为不可⽤，则KE31中⽆法取到该特性的信息），其数据取⾃获利段级别的数据表CE3XXXX和获利段数据表CE4XXXX。KE94与KE34的区别与此相同。
3. KE24与KE25的区别：KE24是取获利能⼒表的实际数据⾏项⽬，⽽KE25是取获利能⼒表的计划数据⾏项⽬。
4. KE30/KE24/KE25等COPA标准的报表，⽆法使⽤排除某个值来进⾏报表查询的，这主要是考虑到系统运⾏性能问题（即便排除了
某个值，系统输出的报表也会将排除的值显⽰出来）。如果需要排除某值的查询，只能使⽤SE16/SE16N对COPA的数据表
CE1XXXX-CE4XXXX进⾏查询.
COPA中常⽤四张表的CE1XXXX/ CE2XXXX/CE3XXXX/ CE4XXXX的解释如下：
CE1****: Table CE1**** stores actual line item data. This table stores allvalues—characteristic values, value field values, and the profitability gmentfor all actual posting in CO-PA. As with the actual line items table, allcharacteristics, including technical T-type characteristics, are included andposted to in CE1****. You can create drill-down reports from the line itemtables. You can display line items in CO-PA, but it is a veryperformance-exhaustive and lengthy process. You should access line items onlywhen you absolutely need to view characteristics that are not part of thegment level.
CE2****: Table CE2**** stores plan line item data. This table stores allvalues—characteristic values, value field values, and profitability gment forall plan posting in CO-PA. All characteristic, including technical T-typecharacteristics, are included and posted to in CE2****. CE3****: Table CE3**** stores data in its first summarized form. Where tableCE4**** stores only combinations of characteristics and creates a profitabilitygment number. CE3**** stores the values of value fields along with theprofitability gment number. CE3**** does not store any actual characteristicvalues (there are no characteristic fields in the databa structure ofCE3****), only the profitability gment number. CE3**** is also utilized bydrill-down reporting to enhance performance.
CE4****: Table CE4**** is the profitability gment level table. CE4SINO storeach possible combination of characteristic values (as they are posted) andassigns each combination a profitability gment number. Profitability gmentnumbers greatly enhance performance on drill-down reporting. CE4**** comes witha standard index and a condary index. SAP will determine which index providesthe best performance.
CE4****_ACCT与BSEG的关系（CE4****_ACCT的具体解释参阅SAPNote:199467）：
BSEG-PAOBJNR = CE4****_ACCT-PAOBJNR
CE4****_ACCT-CE4KEY = CE4****-PAOBJNR
CE4****-PAOBJNR = CE1****-PAOBJNR
⾏项⽬表：COVP (COEP& COBK),
covp-PAOBJNR = CE4****-PAOBJNR
（此部分在获利率报表中很有⽤）
